PEACTICAL  NOTES  FROM  VARIOUS  SOURCES.

The  use  of  Quillain  for  emulsions  was  described  by  S.  A.  McDonnell 
in  a  paper  read  before  the  California  College  of  Pharmacy,  January 
12,  1882..  The  name  quillain  is  suggested  for  the  dry  aqueous  extract 
of  quillaia  [bark,  as  being  short  and  expressive.  The  yield  of  the 
brownish  colored  extract,  made  by  boiling,  is  from  20  to  25  per  cent.  ; 
its  taste  is  sweetish  with  an  acrid  aftertaste,  audit  is  easily  pulverizable 
:and  not  hygroscopic  ;  it  may  also  be]  obtained  in  transparent  scales  b}'^ 
drying  it  on  plates  of  glass,  and  though  ^it  may  be  obtained  colorless 
iby  treatment  with  animal  charcoal,  this  is  not  deemed  necessary,  since 
the  brown  extract  will  yield  a  very  white  emulsion.  It  dissolves 
■quickly  in  water,  and  such  a  solution,  agitated  with  twice  its  bulk  of 
:any  fixed  oil,  very  readily  yields  a  perfectly  homogeneous  emulsion, 
which  on  standing  for  two  or  three  days  may  show  a  partial  separation 
of  turbid  watery  liquid,  this  being  intimately  united  fagain  with  the 
emulsified  oil  by  gentle  agitation.  A  non-separating,  but  much  thicker, 
emulsion  may  be  made  by  using  quillain  gr.fix,  water  si  and  oil  5ix. 
Emulsions  containing  quillain,  but  no  sugar,  have  been  kept  on  hand 
for  a  year  without  spoiling.  The  author  gives  the  following  practical

Emulsion  of  Codliver  oil  luith  Hypophosphites. — F.  Grazer  proposes 
to  prepare  this  with  a  tincture  of  quillaia  made]  by^ 'digesting  4  oz.  of 
the  bark  with  24  oz.  of  water  and  8  oz.  of  alcohol.  Two  ounces  of  the 
tincture  are  heated  to  evaporate  the  alcohol,  mixed  with  2  oz.  of 
glycerin  and  the  necessary  quantity  of  hypophosphites,  when  the  mix- 
ture is  beaten  into  a  creamy  state  by  means  of  an  egg-beater.  Twelve 
ounces  of  codliver  oil  are  next  added  in  small^^quantities,  being  pro-
